FOLDING DAVENPORT-BED.

Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed November 3, 1919. Serial No. 335,341.

T 0 all '20 710m it may concern Be it known that I, ORNAN A. HONSINGER, a citizen of the United States, and resident of Tacoma, county of Pierce, and State of lVashington, have invented certain new and useful Improvements in Folding Davenport- Beds, of which the following is a specification.

My invention relates to davenports, and particularly to the class of folding davenport beds.

The object of my invention is to produce a combined davenport and bed which will have a folding bed section composed of two parts, which when folded will permit a mattress and bedding to be stored out of sight within the davenport frame, and which when opened will form a bed of two parts only lying side by side. with adjacent edges close together, and forming in effect aunitary mattress receiving frame.

Another object is to form such connecting means between the swinging outer bed section and the inner bed section that will be of the simplest character, and which will surely and effectively support the inner section from the outer.

Another object is to provide means for supporting and swinging the seat section of the davenport so that it will be lifted from the frame in opening, and lowered directly thereon in closing to form a tight joint, thus obviating the necessity of using a flexible cloth or leather sheet to cover the joint.

Another object is to provide simple, unitary, and easily attached means for supporting and swinging the clavenport back so that it may be swung upward out of the way to permit the bed to open, and downward when the bed is folded to lock the bed in closed position. A further object is to provide means as described for opening and swinging davenport backs which will raise the back directly upward from contact with the seat section before swinging laterally, thus to avoid scuffing the davenport seat by the back.

Taken as a whole, the object of my invention is to produce a reliable, comfortable and convenient folding davenport bed which operates with the minimum number and simplest of parts, and with the greatest of ease in opening and closing, to form a davenport of the usual appearance and comfort when closed, and a comfortable bed when opened.

My invention comprises the novel parts and combinations of parts which are shown in the accompanying drawings, described in the specification, and defined by the claims terminating the same.

In the accompanying drawings I have shown my invention in the form which is now preferred by me.

Figure 1 is a transverse section through the bed in the open position.

Fig. 2 is a plan view of an end of the bed, the parts being shown in open position.

Fig. 3 is a transverse section through the davenport as it would appear in the closed posltlon.

Fig. 1 is a detail of parts of the bed and seat operating and supporting means, the parts being shown in open position.

Fig. 5 is a detail similar to Fig. 4, parts being shown in the position they would assume in opening or closing.

Fig. 6 is an elevation of a detail of the operating means for the outer supporting legs, and of the mattress-securing frame.

The frame in which the folding bed is secured, and which supports the bed and davenport, may be of any suitable construction. As herein shown, it consists of rails 9 which connect the two ends 90. Reinforcing rails 91, extending across the ends between the rails 9, may be used if desired.

The outer bed section 1 is pivoted to the frame, or to supports 92 secured thereto, by two fixed pivots 11, one at each end of the forward rail 9. As I have shown the bed, and as I prefer to form it, it is composed of structural iron forms, as angles. These lend themselves to various desirable structural combinations. Thus, the support or bracket 92 may be formed as part of an angle, and the bed frame proper may be formed of transverse angles 12 and longitudinal angles 13. The springs 5 and the mattress-receiving wire fabric 50 may be supported from these rails. as at the sides, or from bars 51 supported therefrom and extending across the bed. The details of construction of the bed-frame, springs, and fabric are all old, and their use is a matter of choice. I prefer also to provide means for holding the mattress to the bed fabric 50; those shown consist of a folding head-frame 52, pivoted upon supporting arms 53 which project upward from the mattress receiving side of the frame, and acted upon by a spring 54.. This spring acts to hold the head frame 52 up in the position shown in dotted lines in Fig. 1, or down to clamp the mattress to the fabric, as is shown in full lines. Similar constructions are well known in the art.

The inner bed section 2 'I also prefer to make of structural iron forms. It is composed of transverse angles '22 and longitudinal angles 23. Bars 51, springs 5, and mattress-supporting fabric 50 are supported upon the bed section 2 similarly in every respect to the section 1. The support for the inner edge of the bed section I form as a roller or follower 24 which is secured to the frame at each end. This follower cooperateswith a suitable guide track 94 which is secured to the frame end 9. The track may be inclined slightly forward, and at its upper end has a supporting ledge 95 which supports thebed frame 2 through the roller 24. At its lower end the track 94 may have a pocket 96 into which the roller drops to support the bed frame off the floor when in its closed position.

The connection of the outer edge of the bed section 2 with the swinging section 1 is of a peculiar character. This outer edge of the section 2 lies closely adjacent to the innor or pivoted edge of the swinging section 1 when the bed is opened. At a point 15 upon the section 1 which is somewhat above and preferably inward of its pivot point 11, is pivoted a link 21. At its other end, near the edge of the section 2, the link 21 is pivoted at 25 to the frame of the section 2. This construction, acting in connection with the guide track 94 or any other suitable support for the inner edge of this section, serves to raise the outer edge and the entire inner section 2 to the proper level, and to drag it bodily forward a short distance, for a purpose to be described.

The forward motion of the bed section 2 just described seats the roller 24 securely upon the ledge 95, thereby supporting the inner end of the section. At its outer edge the transverse rails 22 project beyond the longitudinal rails 23 a short distance toward the outer section 1. The inner ends of the transverse rails 12 upon the section 1 are left clear to receive the projecting ends 26 of the rails 22. hen the bed is fully opened the ends 26 rest upon the rails 12, and thereby support the outer edge of the bed section 2. In closing the ends 26 slip off of the rails 12 as the latter tilt, and when the follower 24 has left the ledge 95.

The bed sections 1 and 2 are entirely in dependent of the seat section 4 and the back 3 when opened. It is necessary, however, to remove these latter sections before the bed can be used. I prefer to attach the seat 4 to the section 1 in such a manner that it will swing with the bed section, and when in open position will be swung beneath the bed section out of the way. The inner edge of the seat may be connected to the inner edge of the bed section 1 by means of links 41, which serve as supports for the inner edge of the bed section in opened position, this edge being the outer edge of the bed when it is unfolded. Legs of the type known as grasshopper legs may be employed to support ,the edge of the seat 4 from the floor. These consist of legs 42, pivoted upon the seat, and links 43 connecting the legs 42 and a portion of thebed frame, as 13. As the bed frame is somewhat offset from the corresponding edge of the seat, a loose. joint is required. This is supplied by securing a long bolt16 in the bed framemember 13, and providing a slot 44 in this end of the link 43, and embracing the bolt 16.

. The connection of the outer edge of the seat and the longitudinal rail of the frame is a source of considerable trouble in may folding davenport beds. In many cases the two cannot. be brought together on account of interference by parts of the operating mechanism. In such cases an eifort is made to cover the resulting crack with a flexible strip of cloth or leather. This is unsatisfactory for any length of time, for cloth will become frayed and loosened, andleather or imitation leather will crease and crack. In the cheaper grades of leather, and in imitation leather, which are used most extensively in upholstering such pieces of furniavoid both of the defects described above.

The edge of the seat contacts with the frame rail 9, and thus requires no leather connecting strip. The seat rises directly upward from the rail, and there is no scraping of one part'upon another. To accomplish this result I provide a peculiar construction of links and levers at each end of the seat 4. A lever 45 is pivoted to the transverse angle or bar 12 of the bed-frame '1 at a point 17 which is inward from the pivot point 11 of the frame 1. For the purpose of swinging the seat 4, the bar l2need not be a part of the bed frame. In the present construction it is convenient to so utilize the bed frame bar instead of providing a separate bar. At one end the lever 45 is pivoted to the seat frame as shown at 46, and at its other end it is pivoted at 49 to a control link 47. in turn, is pivotally fixed to the frame, as at 48. The control link 47 and the lever 45 are of nearly the same length, and the control link is considerably longer than the combined distance between the pivot points 17 and 11, and 17 and 49. The pivot 17 The control link 47 is placed inward from the pivot 11 just enough to bring the edge of the seat 4 to rest upon the rail 9, as the link 47 causes the upper end of the lever to swing over in closing. The entire operation is governed by the proper arrangement of pivots and adjustment of the lengths of lever arms. The outer end of the bar 12 and seat 4 are connected by a link 41, as described above.

The lower edge 30 of the back 3 contacts with the inner edge of the seat 4, when the bed is folded, and locks the bed closed. This is shown in Fig. 3. To open the bed it is necessary to swing the back upward out of the way. To avoid scraping and scuifing the leather or cloth covering of the seat the edge 30 should be raised directly upward before being swung backward. This is accomplished by an arrangement of links which fit upon the back and the ends 9 of the davenport frame, and which are so proportioned and related as to cause the back to perform the motion desired.

The back-swinging and supporting device is preferably formed as a unit, ready for attachment to the parts. A section 31 of angle iron is adapted to be secured upon the back 3, and another section 32 is adapted to be secured upon the frame end 9. A pair of links 33 and 34 connect the sections 31 and 32. The upper link 33 is preferably slightly longer than the lower link 34. With parts in the closed position, as shown in Fig. 3, the link 33 is nearly in line with the back, and the link 34 is more nearly horizontal. The link 34, when the back is in raised position, as shown in Fig. 1, is approximately in line with the back, while the upper link 33 is above the horizontal. It is desirable that the distance between the pivots of the links upon the bar 31 be less than the distance between their pivots upon the bar 32. The combination and arrangement as described gives to the lower edge 30, in rising, a motion first straight upward and then backward when clear of the seat 4. Pins or stops 35 and 36 may be employed to limit the downword and the upward swing of the back respectively. These are most conveniently placed upon the bar 32. With the back fully raised, in the position shown in Fig. 1, the effect of gravity upon it will be to produce a component force tending to produce further motion in the opening direction. This will hold the back in this position. When in the closed position, the force of gravity will serve to keep it closed.

I may employ aspring, as 27, attached to the bed section 2, to assist in raising the latter and to open the bed. To open the seat, is swung upward. The seat is then bed, the back, which acts as a lock for the brought upward and forward. This raises the section 1, which in turn raisesthe section 2, as described. As the opening continues the grasshopper legs 42 are opened, and these support the edge of the seat. Its outer edge is supported from the lever 45, as described. The seat supports the inner edge of the bed section 1 by means of the links 41. The inner bed section 2 is supported in the manner described, by its ends 26 and the followers 24 resting on the ledge 95. WVith the mattress clamps 52 at the ends of section 1 swung upward, the bed is ready for use. The bed is opened by two simple operations, raising the back to unlock the bed, and then raising and swinging over the seat.

The bed is closed in a like manner; by raising the section 1, the legs 42 fold up, the seat 4 swings over and finally seats directly upon the rail 9, and the follower 24 drops off of the ledge 95 and follows the'track 94. The projections 26 leave the rails 12, and the section 2 is lowered by the links 21. The mattress is secured to the section 1, and with the bedding it folds and disappears within the davenport. The back is then lowered directly upon the rear edge of the seat, and the davenport is ready for use.
